Intra-domain bandwidth management in differentiated services network

In absence of any link layer traffic controls or priority-queuing mechanism in LAN infrastructure (such as shared media LAN), the subnet bandwidth management based approach of managing bandwidth is limited to only the total amount of traffic load imposed by RSVP associated flows. In such cases no mechanism is available to separate RSVP flows from best effort traffic. This brings the usefulness of the subnet bandwidth manager into question. This uses a combination of integrated services of a specific link layer model based on RSVP and an IP rate-control approach for best effort traffic to manage intra-domain traffic in a differentiated services network.
